Title: Optical space transmitter
Inventor: OTOBE TAKASHI
IPC: H04B10/548
Filed: 1988-03-23
Abstract: PURPOSE:To attain long range optical space transmission stably by sending servo information such as optical axis deviation information or out of focus information with frequency multiplex at a frequency band lower than the transmission band of a main signal. CONSTITUTION:A means 11A sending a frequency multiplex signal between a main signal and a servo signal having a lower carrier frequency than the carrier signal frequency and being subject to angular modulation as an optical beam is provided and a servo signal is extracted from an output of a photodetection section 16A by a BPF 28A. Then the optical system of a transmission-receiver is subject to servo control by circuits 20A, 21A, 22A by using the demodulation output and the servo signal sent to the opposite party is generated from the servo signal band in the output of the photodetector section 16A by a servo information generating circuit 23A. If optical axis deviation or out of focus takes place, the deviation information is detected by the opposite party, sent as the servo signal while being frequency-multiplex onto the main signal, demodulated to be used for the servo correcting the optical axis deviation or out of focus thereby offering excellent servo.

Abstract: PURPOSE: To obtain large reduction gear ratio on the same shaft as an output shaft, by forming this gear by a drive wheel turning positively and reversely, a driven wheel intermittently rotating only in the one direction, a contact piece projecting on a circumference of the driven wheel and a pin projecting to a surface of revolution of the contact piece from an upper portion of a circumference of the drive wheel.  
     CONSTITUTION: A drive wheel 2 is connected to an output shaft 1 repeating positive and reverse revolution, and a driven wheel 3 is disposed onto the output shaft 1 through a pivot 9. The driven wheel 3 is constituted so that it intermittently be turned only in the one direction by meand of a non-teeth ratchet, etc. that use coil springs 10. A pin 5 of the driven wheel 2 collides with a contact piece 4, the driven wheel 3 is pushed at a fixed angle α while a motor reverse by reaction, the pin 5 collides with the opposite side of the contact piece 4 and the driven wheel 3 stops at that location because the wheel 3 cannot rotate this time and also reverses by reaction. Thus, large reduction gear ratio can be obtained without using a number of toothed wheel rows because the driven wheel 3 rotates bit by bit every a fixing angle by means of a ratchet machanism.
